QAIPMT-2004-Ph-2634: NEET 2004 Physics - Class 12 AIPMT-2004-Ph-2634 Solution: If M(A; Z), \(M_p\) and \(M_n\) denote the masses of the…

If M(A; Z), MpM_p and MnM_n denote the masses of the nucleus ZAX_Z^A X, proton and neutron respectively in units of u (1 u = 931.5 MeV/c2^2) and BE represents its binding energy in MeV, then

Multiple Choice Options

  • A M(A,Z)=ZMp+(A−Z)Mn−BEM(A,Z)=ZM_p+(A-Z)M_n-BE
  • B M(A,Z)=ZMp+(A−Z)Mn+BE/c2M(A,Z)=ZM_p+(A-Z)M_n+BE/c^2
  • C M(A,Z)=ZMp+(A−Z)Mn−BE/c2M(A,Z)=ZM_p+(A-Z)M_n-BE/c^2
  • D M(A,Z)=ZMp+(A−Z)Mn+BEM(A,Z)=ZM_p+(A-Z)M_n+BE

Step-by-Step Verified Solution

Mass defect = ZM p + (A �Z)M n � M(A, Z) _ B . E c 2 = ZM p + (A �Z)M n � M(A, Z) _ M(A, Z) = ZM p + (A _ Z)M n _ B . E c 2
